Personally, I find it helps to just treat the interview as a conversation. I know it's easier said than done but it really helps to treat it as it is doesn't matter. You can even go in with the mindset that there's no chance you'll get the job so who cares how the interview goes. Ironically, you'll be able to give off more confidence that way. Not giving a fuck really works (though you'll still need technical competence).
Or maybe, as some smart individual said, the interviews are done differently over wherever you live. Could also be a lot of selection bias here, considering this is ADHD Memes community on Lemmy.
Not sure how much you know about Finnish job interviews tbh.
My peep, of course there's a selection bias here. The selection bias is that interviews are a big problem for ADHD/ASD people. I'm glad you've been lucky enough to not suffer what most of us here do but that's scant consolation for the rest of us.
